We have found that "C nmr spectroscopy is a powerful tool for the determination of the structures of &, trans isomers in the phosphorinane family. It is more definitive than 'H nmr spectroscopy; the carbon signals are well separated and have several unique features pointing to the structure, whereas

## Abstract The piperazinone derivatives have potential application in the pharmaceutical, polymer and textile fields. The present work describes the preparation of a series of new 1,4โdiarylsubstitutedโ2โpiperazinones by condensation of substituted __N__,__N__โฒโbisโ(2โhydroxyphenyl)โethylenediamin
## Abstract ^13^C NMR studies of a series of lactones and ethers containing the spiro[4.5] decenering system were carried out. Complete ^13^C chemical shift assignments were achieved.
The 13C NMR spectra of several 1-(2-hydroxymethylcyclopentyl)and 1-(2-hydroxymethylcyclopentylmethyl)uracils and 5halouracils (X ยผ Cl, Br or I) were fully assigned with the aid of one-(13C, 1H-1H NOE, DEPT) and two-dimensional (HMQC) NMR experiments.
